VILLIAM H. GREEN, OF MERIDEN, CONNECTICUT.

coFFlN-PLATE.

Spccilication forming part of Letters Patent No.` 42,367, dated April19, 1864.

To a/ZZ whom it may concern.-

Be it known that I, WVM. H. GREEN, ot Meriden, in the county ot' NewHaven and State of Connecticut, have invented a new and ImprovedCottin-Plate; and I do hereby declare that the following is full andexact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

The nature of my invention consists in constructin g and attaching aback to a front plate, Figure l, the front'of the back, Fig. 2,corresponding to the back of the front plate, with the exception ot' aslight space to allow for the thickness of the letters and figurespassing between them.

in the back I make an aperture at the side, at the end of two middleridges, A, for the purpose ot' inserting the name, and another slot oropening at the beginning of the two bottom ridges, B, t'or theadmittance of the age. I also make three holes in the back C in order tosolder it to the front plate after the latter is plated, as the solutiongetting between the two plates would spoil them if they were unitedbefore plating.

rI he back I make a trifle smaller than the front plate, to allow thelatter to turn over former at the edge, Fig. 3, the whole forming acompact, finished, double plate, with a space left between the twoplates for the insertion of the name and age, which can be introducedthrough thel slots or openings in the back plate, apertures being leftin the front plate to exhibit them in. The letters and gures I strike upfrom sheet-brass.

In order to disguise Where the letters and figures each come together, Imat or corrugate the ground of them, as shown in Figs. 4 and 5, theridges corresponding to those of the plates; and to prevent the lettersand figures from slipping out, I punch up a period at the end whichseals them to the plate, as shown in Fig. 1, letter D.

What I claim as myfinvention, and seek to secure by Letters Patent, is-

1. The construction of and the attachment of a back to a coflin plate,the said back having corresponding ridges to tit the grooves presentedon the back ot' the front plate, which will admit ofthe insertion ot anyname and age requiring the ordinary numberv t f letters or figures,between it and the front Vplate after the two are united.

2. The invention of the slot or opening in the end or side and middle ofthe back through Which the letters and figures are inserted.

3. Sealing the line of figures or letters by striking up or punching upa period at the end, and the use of letters and tigures struck up fromsheet metal instead of cast ones for this purpose.
